The spec says:
"vkCmdCopyQueryPoolResults is considered to be a transfer
operation, and its writes to buffer memory must be synchronized
using VK_PIPELINE_STAGE_TRANSFER_BIT and VK_ACCESS_TRANSFER_WRITE_BIT
before using the results."
VK_PIPELINE_STAGE_TRANSFER_BIT will wait for compute to be idle,
while VK_ACCESS_TRANSFER_WRITE_BIT will invalidate both L1 vector
caches and L2. So, it's useless to set those flags internally.
